Interesting story about "Isn't She Lovely." If you look at the KRIZ chart for the week of February 26, 1977, the #1 song listed is "Isn't She Lovely/I Wish," by Stevie Wonder. And that is not the only ARSA chart where I've seen the two songs linked together.
They were charting the two songs they were playing at the same time, that's all. Both from "Songs in the Key of Life", which was red-hot at the time.

It's a Google Drive file---don't be alarmed if it takes a few seconds after you press "play" to start. These things are laggy.
